Organization of Archeological Material
Level I: Negligibly climate-sensitive materials
Materials:
• stable stone and fired ceramics
• stable inorganic architectural materials (plaster, mud, daub, brick, and stone)
• dry pollen, flotation, and unprocessed soil samples
• faunal remains Required Climate:
Gradual daily and seasonal fluctuations of temperature and relative humidity can be tolerated.
• Relative Humidity: Above 30% and below 65%. Mold may become a problem above 65%.
• Temperature: Freezing to 100°F. Moderate and cool temperatures are preferred. High temperatures increase deterioration of all materials.
